Hazardous symptoms: The most obvious leaves, dense yellow and green parts of the wounded area near the uplift, the leaves twisted, similar to viral diseases, plant growth is severely blocked, leaves and tender stems can not eat, fruit deformity, yield and quality decreased.
Using a blade, the small bump on the blade is cut open and removed from the inside into a beak. Viewed under a microscope, the beak forms a long, conical, orange-yellow color. By looking up the data, the dragonfly is mainly wintering in the buds of other plant gaps near the planting land. In mid-April of the following year, when the winter buds begin to bloom green, the overwintering pupa starts to produce pupa. From late May to early June, the pods are transferred to the new leaves and spawned. Cockroaches penetrate into the leaf tissue to form pupa, and the damage from mid-August to mid-September to peak. In mid-November, the temperature dropped into helium and turned into winter. In addition, it has been found that there are an unequal number of adulterants on the lobe of the aphid and mule belly and foot.
Control methods: Chengyu is in the critical period of prevention before and after wintering. When a large number of larvae appear in time, the pesticide is sprayed in time to reduce the pest density. It can be sprayed with 50% miticidal suspension for 600 times or one hundred times for 1000 times, or 1.8% for abimycin for 3000-4000 times. . According to the experience of the local old farmer: to master the local exposing stage or exposing stage, the use of ultra-low volume spray method, spray 50% of the enemy oil mist mixed with diesel 1:1, 200 grams of medicine with mu Liquid effect is better.
